Disabling MTCH2 Protein Boosts Fat Burning, Prevents Obesity

Summary

Story summary

Researchers at the Weizmann Institute disabled protein MTCH2 (“Mitch”) in mice and human cells, boosting fat burning and preventing obesity.
Mice lacking Mitch stayed lean, grew extra muscle fibers, showed higher stamina and improved heart function, while human cells entered an energy-shortage state and shifted to fat oxidation, lowering membrane fat content.
Deleting Mitch from progenitor cells blocked new fat-cell formation, offering a route to preserve muscle while targeting obesity.
